Intranasal midazolam for treating acute respiratory crises in a woman with stiff person syndrome.
Stiff person syndrome (SPS) is a rare neurologic disorder characterized by progressively worsening rigidity and spasms of the axial and limb muscles. Dyspnea has been recently recognized as a common symptom in SPS,1 and life-threatening respiratory crises have been occasionally reported and suspected to be responsible for sudden death in these patients.2,3 The pathophysiologic mechanisms of these respiratory manifestations remain unclear. Some authors have hypothesized that rigidity and/or spasm of the muscles of the trunk could prevent normal rib cage movements and excursion of the diaphragm.1
Compliance to ventilatory treatment in a cohort of patients on home CPAP or NIV: analysis by diagnosis, treatment type, and comorbidities
Background: Patients on home continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV) show large variability in compliance to treatment. Aim: To identify predictors of poor compliance, we evaluated compliance to treatment in patients with obstructive sleep apnea (OSA), obesity hypoventilation syndrome (OHS), and OSA-chronic obstructive pulmonary disease (COPD) overlap syndrome. Methods: We analyzed clinical and compliance data provided by a single home care provider, in 602 patients (n=442 OSA, males (M) 308; 38 OHS M=15, and 122 overlap M=111) on home CPAP/NIV in the province of Agrigento, Italy, after one year of treatment. The following variables were considered: age, …
Use of autobilevel ventilation in patients with obstructive sleep apnea: An observational study.
Continuous positive airway pressure (CPAP) is the first-choice treatment for obstructive sleep-disordered breathing. Automatic bilevel ventilation can be used to treat obstructive sleep-disordered breathing when CPAP is ineffective, but clinical experience is still limited. To assess the outcome of titration with CPAP and automatic bilevel ventilation, the charts of 356 outpatients (obstructive sleep apnea, n = 242; chronic obstructive pulmonary disease + obstructive sleep apnea overlap, n = 80; obesity hypoventilation syndrome [OHS], n = 34; 103 females) treated for obstructive sleep-disordered breathing from January 2014 to April 2017 were reviewed. Positive airway pressure titration was …
